Abstract
The invention discloses a production process of drainage sand, which comprises the following steps: (1) the recycled waste magnesia-chrome brick is subjected to primary iron removal, jaw crushing and roller rough addition to 8mm granular material iron removal, and then is processed into 3mm granular material iron removal through a crusher, so that the semi-finished magnesia-chrome sand material is obtained. (2) Adding the semi-finished magnesite-chrome sand, the quartz sand and the additive into a planetary stirrer in sequence according to the technical proportioning requirement, and stirring for 5 minutes to obtain the finished product. (3) And (5) matching and packaging according to the size of the drainage sand of the client. The invention has the beneficial effects that: the waste magnesia-chrome bricks are used as raw materials, so that the effects of environmental protection and production cost reduction can be achieved, and in addition, the self-opening rate of the magnesia-chrome bricks can be greatly improved through the drainage sand prepared by the process.
Description
The application is a divisional application of an invention patent with the application date of 2015, 07, 10 and the application number of 201510415737.4 and the name of 'a production process of drainage sand'.
Technical Field
The invention belongs to the technical field of casting equipment manufacturing in the metallurgical industry, and particularly relates to a production process of drainage sand.
Background
The prior production process of the drainage sand in the prior art has the problem of environmental pollution, and the drainage sand produced in addition has low self-opening rate and high cost.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a production process of drainage sand, which is environment-friendly, low in production cost and high in self-opening rate of the produced drainage sand.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the production process of the drainage sand is characterized by comprising the following steps of:
(1) after picking, carrying out primary selection iron removal, jaw crushing and roll machine rough machining on the recycled waste magnesia-chrome bricks to obtain 1-8mm granular materials for iron removal, and then processing the granular materials into 0.1-3mm granular materials for iron removal through a crusher to obtain semi-finished magnesia-chrome sand materials;
(2) adding the semi-finished magnesite-chrome sand, the quartz sand and the additive into a planetary stirrer in sequence according to the technical proportioning requirement, and stirring for 3-5 minutes to obtain a finished product;
(3) and (5) matching and packaging according to the size of the drainage sand of the client.
The invention has the beneficial effects that: the waste magnesia-chrome bricks are used as raw materials, so that the effects of environmental protection and production cost reduction can be achieved, and in addition, the self-opening rate of the magnesia-chrome bricks can be greatly improved through the drainage sand prepared by the process.
