Embodiment 1
[0047] First of all, the sorted waste clay soup brick raw materials are subjected to primary magnetic separation with a belt magnetic separator, and the large block raw materials after magnetic separation are processed into small pieces of 20*20cm by a jaw crusher, and then sent to the Double-roll crusher, processed into small particles with a particle size of ≤4mm, and then a three-roll magnetic separator with a magnetic induction intensity of 3000 is used to conduct secondary magnetic separation on the small particles, and then the small particles after magnetic separation are separated by the second elevator The granules are sent to the vibrating sieve, and sieved to obtain raw materials with a particle size of 4-1mm. Then add 1% white carbon black anti-high temperature additive to the raw materials of the specifications, knead and stir in the kneader, dry in a baking kiln at 150°C, and finally inspect and pack to obtain a molded steel chassis masonry Material.
Embodiment 2
[0049] Implementation method is the same as Example 1, wherein the add-on of white carbon black is 1.5%.
Embodiment 3
[0051] Implementation method is the same as Example 1, wherein the add-on of white carbon black is 2%.

Abstract
The invention provides a novel die-casting steel chassis masonry material and a manufacturing method thereof. The present invention utilizes the characteristic that the physical performance and chemical composition of the discarded clay soup bricks after use in the production of die-casting steel and quartz sand are basically similar, and the particles extracted and processed from the discarded clay soup bricks are used as raw materials to replace the quartz sand. The anti-high temperature additive makes the chassis masonry material with low cost and good high temperature performance. The use of the die-cast steel chassis masonry material in the invention realizes the recycling of waste resources after use in the iron and steel industry, and solves the waste of resources and environmental pollution caused by waste bricks.
Description
technical field [0001] The present invention relates to chassis masonry material and its manufacturing method, in particular, the invention relates to a new die-cast steel chassis masonry material and its manufacturing method. Background technique [0002] So far, quartz sand and clay refractory bricks are the main traditional consumable materials for chassis masonry in die casting production. Among them, quartz sand is the most commonly used. It is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO 2 , its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point is 1650 ° C, so it is widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, Plastic, rubber, abrasive and other industries. However, in the process of mining, transportation and use of quartz sand, its powder has the disadvantages of...
