Embodiment 1
[0022] In the embodiment, the mass percentage of steel type Ti is above 0.4%, and the produced section is 150*1600mm.
[0023] The continuous casting process of producing high titanium wear-resistant steel on the straight arc slab continuous casting machine,
[0024] (1) The slab is poured and filled with inert gas argon in the tundish, and the filling time is maintained at 10 minutes;
[0025] (2) The continuous casting process adopts the whole protection pouring: the ladle to the tundish is poured with a long nozzle argon-sealed mold slag, the tundish to the crystallizer is poured with a slide-type submerged nozzle, and the molten steel in the tundish is protected by a double-layer covering agent. One layer is alkaline covering agent, and the upper layer is slag;
[0026] (3) The main component weight percentage of the mold flux laid on the surface of the crystallizer is: SiO 2 : 20-40%, Al 2 o 3 : greater than 0 and ≤ 8%, CaO: 20-40%, Fe2O3: greater than 0 and ≤ 5.5%,...
Embodiment 2
[0032] In the embodiment, the mass percentage of the steel type Ti is above 0.4%, and the produced section is 150*2400mm.
[0033] The continuous casting process of producing high titanium wear-resistant steel on the straight arc slab continuous casting machine,
[0034] (1) The slab is poured and filled with inert gas argon in the tundish, and the filling time is maintained at 15 minutes;
[0035] (2) The continuous casting process adopts the whole protection pouring: the ladle to the tundish is poured with a long nozzle argon-sealed mold slag, the tundish to the crystallizer is poured with a slide-type submerged nozzle, and the molten steel in the tundish is protected by a double-layer covering agent. One layer is alkaline covering agent, and the upper layer is slag;
[0036] (3) The main component weight percentage of the mold flux laid on the surface of the crystallizer is: SiO 2 : 20-40%, Al 2 o 3 : greater than 0 and ≤ 8%, CaO: 20-40%, Fe2O3: greater than 0 and ≤ 5...
