Problems solved by technology

[0003] 1. The start-up time of several large motors is not staggered, and the grid fluctuation phenomenon is serious;
[0004] 2. Due to the lack of coordinated treatment, it is easy to cause local blockage; and the equipment has a long empty running time, a large load, and high equipment loss

Embodiment Construction

[0023] A cold steel slag treatment control method of the present invention, it comprises the following steps:

[0024] At the beginning of the production line, input signals to the processor through the intelligent input interface to start two equipments: the impact crusher P14 and the hydraulic protection jaw crusher P4; here, first start the two high-power crushers to avoid multiple crushers in the back. When the equipment is started, the power grid fluctuates seriously.

[0025] After an interval of 10 to 20 seconds, each operating device is interlocked and opened in the order of the cold steel slag processing line from the back-end equipment to the front-end equipment; the opening interval of each equipment is 1 to 3 seconds. This can prevent localized material clogging.

[0026] When the production line stops, all equipment will be interlocked and stopped in the order of the cold steel slag processing line from the front-end equipment to the back-end equipment. Similarl...

Abstract

The invention discloses a control method for cold steel slag processing, in which signals are inputted to a processor through an intelligent input interface. Firstly, two crushers are started, and operating equipments are sequentially started at regular intervals; a production line is interlockingly started in two steps, so that the fluctuation of a powder network is minimized; when the production line is stopped, the equipments are sequentially stopped in reverse steps. According to the invention, local material stacking is avoided; and the load is low, thus to reduce equipment loss.

Description

technical field [0001] The invention relates to a control method for steel slag treatment, in particular to a control method for cold steel slag treatment. Background technique [0002] With the development of the steel industry, the amount of steel slag also increases. After the hot-melt steel slag is processed, it is excavated and loaded with loaders, electric shovels and other equipment, and then transported to the waste slag yard. The stockpiling of steel slag not only occupies a large amount of cultivated land and pollutes the environment, but also 7% to 15% of steel can be recovered from steel slag. Steel slag can be used as smelting flux, steel slag cement, construction aggregate, agricultural fertilizer and soil conditioner after processing. Therefore, the treatment and comprehensive utilization of steel slag can produce huge economic and social benefits. The steel slag treatment workshop recycles the cold steel slag, and the cold steel slag treatment includes cru...
