Austenitic Stainless Steel 347H belongs to high-carbon Cr-Ni austenitic stainless steel containing niobium, due to the stabilizing element Nb, its stability is very strong, good resistance to intergranular corrosion and resistance to acid stress corrosion, with good weldability, high-temperature strength and plasticity, is widely used in the boiler, power generation, petroleum, chemical…

Through optimizing temperature control process the mechanical properties of wire rod can be improved. According to the wire rod organization mechanism transformation during production, combined with the requirements of the production conditions of each steel specification, targeted adjustment of the heating temperature, spitting temperature and the operation of cooling fans can…

The state of rolling mill will influence the operation of the whole production line, it is necessary to do routine maintenance for smooth operation of the whole line. (1) Keep that all lubrication stations operate normally and the pipeline has no leakage; (2) Hydraulic stations work steady, the pipeline has…

How is the subcutaneous bubble of continuous casting billet formed? Under the skin of the billet there are large bubbles growing in the direction of columnar crystals with diameter and length of more than 1 mm and 10 mm respectively. These bubbles, such as those exposed to the outside, are…

During production and operation process of induction furnace, every operator shall observe the key dangerous factors and do good protection for himself and others. Explosion risk Medium frequency furnace due to refractory masonry or baking is not qualified, serious corrosion of the furnace lining, cooling water pipe defects or water…

Correctly apply induction furnace is related to the actual production efficiency. Some factors shall affect the work efficiency of the intermediate frequency furnace. Intermediate frequency furnace power The power of the intermediate frequency furnace should be based on the material of the heated metal, heating temperature, heating time and heating…

Argon, an inert gas, does not dissolve in molten steel and does not react with any element. It is a very ideal stirring gas, so it is widely used. In terms of agitation, nitrogen is the same as argon, and nitrogen is cheap, but nitrogen can be dissolved in molten…

Characteristics of Induction heating include below (1) High heating temperature, and non-contact heating. (2) High heating efficiency. (3) Fast heating speed. (4) The temperature is easy to control. (5) Can be localized heating. (6) Easy to realize automatic control. (7) Good working environment, almost no noise and dust. (8) Less…

High production cost affects the product competitiveness of steel factory, for the production of high-strength steel bars, there is a workable solution to reduce alloy cost to employ Ti replacing N-V for microalloying. The strengthening effect of niobium on steel is mainly fine grain strengthening and diffusion strengthening. Niobium added…

The factors affecting the rolling force are: Absolute reduction In the roll diameter and friction coefficient of the same conditions, the contact area between rolled part and roll becomes large along with increase of absolute amount of press-down, so the rolling force increases. Roll diameter The contact area increases as the roll diameter increases, while the…
