Self straggle fast casting method used for battlefield emergency fast shaping of armoured car component part

Abstract

A self-spreading high-speed casting method for emergency manufacture of the parts for armoured car includes such steps as preparing aluminothermic welding flux, preparing mould from furan resin sand, loading said welding flux in resin crucible burying the igniting TiC flux in welding flux, igniting, self-spreading aluminothermic reaction to obtain molten iron, casting, and solidifying.

Description

Technical field:

[0001] The invention relates to a self-propagating rapid casting method, which is mainly suitable for emergency rapid prototyping of armored vehicle parts on the battlefield. It belongs to the technical field of metal casting. Background technique:

[0002] Emergency repair of armored equipment on the battlefield is an effective means to maintain the survival rate of armored vehicles on the battlefield and improve the regeneration ability of combat effectiveness. The replacement and repair of seriously war-damaged parts on the battlefield is a very heavy repair method. It is often the way to go. However, the spare parts on the vehicle are limited, and there is an urgent need for a technology to quickly produce parts or blank parts without electricity, gas and simple equipment, so as to solve the problem of missing parts when replacing parts.

[0003] In the field of SHS, the ingot is obtained by selecting a high exothermic combustion system so that the co...
