Embodiment

[0023] Embodiment: a casting of armored vehicle carries out self-propagating rapid casting application test:

[0024] The weight of the casting is 4kg, and 8kg of aluminothermic casting flux is used. According to the order of adding acid first and then resin, furan resin and catalyst are prepared in proportion, quickly mixed with silica sand in a plastic bag and then sanded. Its specific process steps are:

[0025] 1. Preparation of aluminothermic casting agent

[0026] 1. Basic composition of aluminothermic casting flux:

[0027] In addition to 19-25% aluminum powder with a particle size of 200-300 mesh and 55-60% iron oxide with a particle size of less than 100 mesh and a carbon content of less than 0.5%, the aluminothermic casting flux used in this experiment needs to be formulated. Add appropriate amount of alloying agent, slagging agent and auxiliary flux, and their respective components and functions are described as follows:

[0028] Adding material - alloying agent ...

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...
