Exports are mainly to hong kong, south-east asia, latin america, etc. The export producers are mainly steel mills in liaoning, hebei, beijing, shanghai and other provinces and cities. Angular steel varieties range from large to small and special shaped agular steel to the export of medium agglomerations such as 6, 7. The surface mass of skin-quality agglomerated steel is set out in the standards and generally requires that no adverse defects in use, such as layers, scars, cracks, etc., should be present. The permissible range of differential shapes of angular steel is also provided for in the criteria, which generally include, for example, curves, edges, thickness, contours, theoretical weights, and provides that angular steel shall not be subject to significant reversals。
During the week, the domestic steel market boomed and the overall deal was quite satisfactory. The tangshan steel market is operating in a poignant shock. At the beginning of the week, s355jr steel prices increased significantly, but in view of the large reduction in the price of steel in the previous period, the merchants questioned the persistence of steel price increases, and there was still an empty mind about the back market. Close to the end of the week, the price shock of the black chain goods screwd steel went down, the trade in finished steel was normal, and the enthusiasm in the market declined. On the one hand, the current terminal demand is shrinking, steel prices are still holding back, most traders are waiting for winter reserves, and the post-market is expected to be empty; on the other hand, as the heating season is limited, steel resources will become more compact and, given the current profit margins of steel, the firm will be more expensive. As a result of the current situation, there has been no apparent intention to purchase the depots, owing to the obstruction of the sale of finished steel, the poor delivery of the mills, and the cautious wait-and-see attitude of the mills. In combination, it is expected that the late steel market will operate with strong shocks。
During the week, the domestic iron market was still dominated by the following actors, and the market was generally closed. As a result of the continuing decline in coke prices, steel plants stopped purchasing raw iron. The difficulty of delivering the iron plant, the continued increase in stock, the downward revision of the price increases, the suspension of the offer for some of the plants and the lack of or no market access in most areas. The current price of steel, finished steel, has declined and rebounded. It has boosted the mentality of the raw iron market, but the deal has not improved significantly. In the current situation, the demand for raw iron is weak, the market climate is weak, but the price of raw iron is already low, the willingness of traders to continue to decline is low, together with stable prices for raw materials, stable costs and limited space for lower prices. As a result, the domestic iron market is expected to operate at a steady and weak pace。

(1) straight-frowsing system. A straight-through system means a system of two open legs of a working-word steel hole on the same side of the axle and parallel to the axle. The advantage is that the axle is small, the axle is small, it is small, it does not need a working slope, it is small in size, and it is more perforated under certain lengths。

The convection structure consists of one, two, three of the figures in figure 2, which is linked by a screw and is then secured by a bolt on the condensed plate 7. Magnificents and condensed pallets use small gaps to match h7/h6 and adjust and replace them, and the balance of the convex and dimples is ensured by the guidance kit 8 and 9. The two-35-degree slopes on the jiggles 1 and 3 are the blades of the cut-out slabs, which are also the parts of the production that are severely worn, with the use of cr12 mv material, and the hardness of the flint in the range of hrc58-62, with the potential for progressive molds having a life of about 8,000 times。
Categorized by surface treatment of a piping tube: thermal zinc plating tube, electroplating zinc piping tube, oil coating tube, acid washing tube. Classification by wall thickness: superheavy wall tube, thick wall tube and thin wall tube. Classification by standard of production: national probator tube, daily probator tube, british probator tube, united states probator tube, european probator tube, non-tebster tube. Categorized by mechanics: steel tube mechanics are important indicators of end-use performance (mechanical performance), depending on the chemical composition and thermal treatment system of the steel pipe。
The s355jo588,300h steel price is recommended for high quality, and at the end of the week market confidence has been boosted, with trade and market prices rising. According to analysis, prices are weak in the construction steel market. The average price of the country's main market-specific screwd steel varieties was $3918 per ton, a decline of $11 a week. Based on inventory data, overall stock levels were lower than in the same period last year, although both social stocks and steel plant stocks continued to accumulate, in the case of a clear fall in screwd steel production. Prices generally went down in the board market. The price of the hot rolls is weak, with the market average of $3733 per ton for the main market of the country's main product, a drop of $10 per week。
The length of the welding extension should be as short as possible and can be effective in reducing the welding of the rectangles. Gas protection welders generally use the straight-flow inverse-relationship method because the arcs are subject to positive spot pressure, with a sharp increase in splash and large particles. Welding back roads with wires. When medium currents are used to regulate gas protection welding, because the arcs are short and both the melting drops and the smelting pools are constantly moving, and because the smelting drops and smelting pools are more susceptible to short-circuit processes, gas protection welding, in addition to the large drip-like exclusion transition, is partly a short-circuit transition, with some electrical senses in the welding circuits, which slows short-circuit current growth, so that welding can be properly reduced。
2. Problems with the design of sluice blades, combined with the actual production situation, are designed in the shape shown in figure 2 (in the case of 100 # sluice steel). The width of the upper blade was changed from 100 mm to 99 mm, reducing the edge of the upper blade in the right direction and improving the cut quality of the two angles of the tank steel; the size of the lower blade was changed from r8mm to r7mm, increasing the number of cutting overlaps between the two angles and improving the cut quality of the shoulder of the tank; the width of the lower blade was changed from 79 mm to 80 mm and the width of the lower edge was changed from 97 mm to 94 mm, so that the edge of the lower edge of the clipped leg was less than the slant of the steel formed in the tank, so that there was no simultaneous force on the leg and the lower direction of the clipping, thereby reducing the cut strength and improving the quality of the cut。

By symmetrical distribution, the effect of side forces is eliminated, so that the resonance of the mould and the slider is balanced and balanced. On the other hand, because of the fact that the flash gap is a non-confined impulse and the discharge capacity is very small, it is possible not to design an offloading device, which is easy to manipulate, the mould structure is simple because of the absence of a side-direction device, symmetrical distribution, and it is easy to process, manufacture and adjust the mould。
