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…
High-aluminium steel production technology High-aluminium steel with high strength, high toughness, low density, low cost and other advantages, widely used in automotive, energy and other key industries. However, with the substantial increase in the aluminium content of high-alumina steel, its production difficulty increases steeply, especially in the continuous casting of…
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…
Two new national standards will be performed in February 2024 YB/T 6110-2023 Hot rolled steel plates and strips of chromium-manganese-nickel-nitrogen austenitic stainless steel This document specifies the chromium – manganese – nickel – nitrogen austenitic stainless steel hot rolled steel plate and steel strip order content, grade, size, shape, weight,…
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…
