Die casting and continuous casting are used in heat resistant steel
Stainless steel and other special steel are commonly used in industry and in our daily lives. And there are a lot of technology steel making. Heat resistant steel casting can be divides into two types, die casting and continuous casting. And the die casting is most used in heat resistant steel production. In recent years, the continuous casting develops fast. And high alloy heat resistant steel, both die casting and continuous casting, will take protective measures. Because of that, if the steel liquid contacts with air,chromium, manganese, silicon, titanium, aluminum etc,steel will have reaction with the oxygen and nitrogen in the air to produce secondary oxide, leading to the serious influence steel internal quality and ingot, billet surface quality.
Heat resistant steel die casting generally uses bet method. Molten steel is poured into the steel tube, and the injection of ingot plate channel from the bottom into the mold. At the same time, a number of casting ingot. Bet method has the advantage of liquid steel in the mold inside rosing steadily, no splash. Besides, to take measures to protect casting, steel surface quality is good and the production efficiency will be higher. The disadvantage of this method at the same time is that the whole die operation is more complex, leading to lossing more metal and molten steel yield is relatively low.
Heat resistant steel continuous casting steel can not only improve the yield of molten steel, improve the comprehensive, but also save cogging process. This greatly reduces the energy consumption and the production is efficiency improved significantly. Continuous casting has uniform organization and small segregation. Also, the continuous casting production labor intensity is lower. So, continuous casting is an important measure in meheat-resistant steel production to improve quality and to reduce cost. This important measures is also one of the most important marks of modern production.
