Abstract
The invention belongs to the technical field of alloy preparation, specifically relates to a preparation method of an unfired fly ash aluminum alloy block, and mainly aims at solving the problems of heavy waste, low utilization rate and environmental pollution of the fly ash. The technical scheme adopted is as follows: the preparation method of the unfired fly ash aluminum alloy block comprises the steps of (1) stirring the fly ash into spherical particles having a diameter ranging from 3 to 5 centimeters, (2) pressing the spherical particles obtained in the step (1) into a desired block under pressure of 6.5-7.5 square centimeters, and (3) feeding boiler vapor to a non-firing kiln under discharge pressure of 5 kilometers per square centimeters and then sending the block obtained in the step (2) to the non-firing kiln for reactions of three stages, and finally, obtaining the aluminum alloy block. The preparation method is simple, high in utilization rate and environment-friendly.
Description
Technical field
The invention belongs to alloy preparing technical field, be specifically related to a kind of preparation method of fly ash baking-free silumin piece.
Background technology
There is abundant coalfield in China, and coal is elementary composition by carbon, silicon, aluminium, calcium, iron, sulphur, titanium etc.Many fuel-burning power plant that distributing in China various places, the coal of the different quantities that burning every day, is producing the flyash of enormous amount.The composition of flyash is mainly sulfurous acid silicon, aluminium sulfite, calcium oxide etc.Have a large amount of flyash in Shuozhou City god two power plant, these flyash are wasted more, and utilization ratio is low, has also caused certain environmental pollution.
Summary of the invention
The present invention is serious mainly for flyash waste, utilization ratio is low and the problem of contaminate environment, and a kind of preparation method of fly ash baking-free silumin piece is provided.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of preparation method of fly ash baking-free silumin piece comprises the following steps:
(1) flyash being stirred into diameter is the ball-type grain of 3～5 centimetres;
(2) the ball-type grain of step (1) is depressed to needed module at 6.5～7.5 cm2 pressures;
(3) send unburned kiln by feedwater vapor outlet port pressure by 5 kilograms of cubic centimetres, again the module of step (2) is sent into unburned kiln and carry out the reaction of three phases, first stage: with the temperature rise rates of 5 degree per hour, allow the temperature of unburned kiln rise to 40 degree by 0 degree, 40 degree constant temperature 2 hours; Subordinate phase: with the temperature rise rate of 10 degree per hour, allow the temperature of unburned kiln rise to 60 degree by 40 degree, 60 degree constant temperature 4 hours, the phase III: with the temperature rise rates of 15 degree per hour, allow the temperature of unburned kiln rise to 120 degree by 60 degree, within 4 hours, make silumin piece at 120 degree constant temperature.
The present invention adopts technique scheme, the flyash of power plant is carried out to second stage employ and produce silumin piece, for a new direction has been opened up in coal ash secondary utilization, has also reduced the pollution of environment simultaneously.
