Abstract

The invention discloses a valve steel continuous casting crystallizer functional protection material. The material comprises the following raw material components including, by weight, 36.0-42.0% of pre-melt materials, 14.0-17.0% of wollastonite, 9.0-11.0% of fine glass powder, 3.0-5.0% of lithium carbonate, 7.0-9.0% of fluorite, 2.0-4.0% of sodium fluoride, 3.0-5.0% of cryolite, 10.0-12.0% of graphite carbon, 2.0-3.5% of carbon black and 2.0-3.5% of a binder. According to the valve steel continuous casting crystallizer functional protection material, the thermal insulation effect and the melting effect are guaranteed, furthermore, pulling break, slag inclusion and depression of casting blanks are effectively prevented, and the non-cleaning rate of the surfaces of the obtained casting blanks reaches up above 98%.

Description

technical field [0001] The invention belongs to the technical field of metallurgical auxiliary materials, and in particular relates to a continuous casting crystallizer functional protection material for valve steel. Background technique [0002] Internal combustion engines include gasoline engines and diesel engines, which are used in automobiles, motorcycles, tractors, ships, diesel locomotives, tanks, oil drilling rigs, construction machinery, mobile power stations, etc., and play an important role in the national economy and even national defense and military industries. The development of internal combustion engine valve steel is closely related to the development of internal combustion engines in my country. For decades, especially since the reform and opening up, advanced internal combustion engines from Germany, the United States, Japan, France and other countries have been introduced into my country, which has rapidly improved the level of internal combustion engine...
