equipment
Working vacuum can reach below 67Pa, hydrogen content in the production process can be controlled below 1.5ppm, oxygen content can be controlled below 10ppm, to ensure that the product has excellent internal quality.
With the function of protecting atmosphere, the whole process of smelting in argon sealed environment, the oxygen and nitrogen increase in the smelting process is small, to achieve the purpose of low oxygen, low nonmetal inclusion electroslag ingot production.
The maximum rolling force is 10000KN, the maximum opening degree is 600mm, and the pressing accuracy is ±0.25mm. Meet the nickel alloy, valve steel, hot die steel and other steel opening rolling.
Including 24 mill and finishing mill set, production specification range Ф5.0-34mm wire and large coil, with stepping furnace, to meet the requirements of a variety of materials rolling production.
Including 4 reducing mill, increase the wire rod size accuracy, can control the diameter of Ф5.0-15mm diameter range of wire rod ellipticity below 0.15mm, can meet the requirements of straight mill.
The temperature range of production process is 450-950°C, and the temperature uniformity in the furnace is good. The temperature difference between the upper and lower 10mm of the workpiece can be controlled within ±5°C, which can meet the requirements of high performance annealing of die steel and special stainless steel.
The process temperature range is 700-1100℃, which can meet the solution treatment requirements of most stainless steels, and obtain uniform and stable structure and properties of products.
Nitrogen to protect the atmosphere, furnace temperature uniformity is good, temperature fluctuation within 10℃, meet the requirements of various steel performance stability and decarbonization layer control.
