Embodiment
[0034] After 1 ton of high-speed steel molten steel is smelted in an induction furnace or an electric furnace, it is poured on a twin-roll thin strip continuous caster. The process of the present invention is used for pouring during the pouring process. The results are as follows:
[0035] Casting roll
[0036] Conclusion: With the above process parameters, high-speed steel cast strips with stable quality can be obtained that meet the requirements of industrial production.

Abstract
A dual-roller conticasting technology for casting the high-speed steel band includes such steps as preheating the side plates to 900-1400 deg.C, pouring molten high-speed steel without seam between two rollers to form molten bath, and regulating the seam between rollers for casting at 35-100 m / min.
Description
Technical field [0001] The invention belongs to the field of metal casting, and in particular relates to a production process of double-roll thin strip continuous casting high-speed steel by high-temperature baking of side sealing plates before pouring and zero roll gap pouring. Background technique [0002] The twin-roll thin strip continuous casting technology can directly cast molten steel into thin metal strips, and is mainly used in the production and research of stainless steel and carbon steel. There is little research on high-speed steel. [0003] At present, there are more than 40 double-roll thin strip continuous casters at home and abroad that have conducted laboratory or industrial experiments, and there are related records. Such as: [1] 1996, (3): 25 "World Metal Herald" Bai Bingzhong's "New Progress in World Strip Steel Continuous Casting Technology"; [2] 1997 (2) "Special Steel Technology" Weekly Code, Pan Fusheng, Ding Peidao" Application of twin-roll continuous c...
