One Of High Level Metal Ferro Silicon Aluminum

Filter press anti-resistance agent is used in the production of water purification agent polyaluminum chloride process, which can prevent the formation of silica gel and solve the problem of filter press blockage; The added filter press anti-resistance agent can be combined with silicic acid to form polysilicon ferro silicon aluminum, which has the effect of strengthening the water purifier and turning silica waste into treasure; The production cost of filter press anti-resistance agent is low, so it can reduce the production cost of polyaluminum chloride of water purification agent.

1.A method for preparing ferrosilicon-aluminum-calcium alloy by high-temperature smelting of coal gasification slag involves the field of metallurgical technology, and is carried out in the following steps: crushing coal gasification coarse slag, medium slag and fine slag into powder with a certain particle size; Mix the crushed powder with additives in a certain proportion; The mixed powder is pressed into pellets; The pressed pellets are dried at 50°C~200°C; The pellets are smelted at high temperature at 1200°C~2200°C to obtain alloys with certain compositions; The alloy is separated from the slag and then cast, so as to obtain the iron-silicon-aluminum-calcium alloy. The method of the present invention uses coal gasification slag to prepare silicon-iron-aluminum-calcium alloy, provides a new way for the comprehensive utilization of coal gasification slag, reduces resource waste, turns waste into treasure, and realizes the recycling of resources.
