Abstract

The invention discloses a high-strength heavy-duty truck fifth wheel cast steel and a preparation method thereof, comprising modified riser covering agent, modified epoxy resin coated sand, modified expanded graphite, modified epoxy resin, polyurethane, C , 1Si, Mn, Ni, Cr, Mo, Ti, Al, B, rare earth elements. The surface modification of expanded graphite with ionic liquid can be more uniformly dispersed in the covering agent. After instantaneous expansion, the density is lower under the same mass, and the thermal conductivity is also smaller, which can maintain the temperature of molten steel for a longer period of time. Modified epoxy resin-coated sand can speed up the curing speed during the preparation of the cast steel traction seat, and the thermal insulation system formed with the riser covering agent when curing and cooling down can speed up the overall curing speed and reduce the temperature of molten steel in the riser. Solidification speed, before the cast steel traction seat is prepared, a high-strength shell is prepared by vacuum negative pressure shell casting technology, and the composite with the outer shell makes the traction seat have higher strength.

Description

technical field [0001] The invention relates to the field of cast steel, in particular to a high-strength heavy-duty truck traction seat cast steel and a preparation method thereof. Background technique [0002] Steel casting is the most flexible way to manufacture complex parts. The application of advanced casting technology has brought new vitality to the manufacturing industry. At the same time, the foundry industry has encountered great challenges from the inside and outside of the foundry industry. In China, casting has a long history. [0003] However, the traditional steel casting method has a slow solidification speed in the casting process and a complicated process, which makes the preparation of steel castings take a long time, so it has great development prospects for less preparation time and energy consumption of cast steel. of. Therefore, it is very necessary to prepare a high-strength heavy-duty truck fifth wheel cast steel with fast curing speed, simple pro...
