Abstract

The invention provides an organic silicon slag exothermic and insulating riser sleeve and a preparation method thereof. The insulating riser sleeve comprises the following raw materials of organic silicon slag, an oxidizing agent, refractory aggregate, an ignition material, a fluxing agent and a binder. According to the organic silicon slag exothermic and insulating riser sleeve, the organic silicon slag is used as a heating agent to partially or completely replace aluminum powder and aluminum slag, so that the riser sleeve has the advantages of energy conservation and emission reduction, low cost, low ignition temperature, short ignition time, excellent heating stability, no deflagration, long heat-insulating time, easiness in storage and the like; the problems of high cost, short storage period, deflagration and the like of the existing exothermic and insulating riser are solved; and during casting, under the combined action of heating and long heat preservation, the temperature of molten metal in the riser is increased through released heat, the solidification time of the molten metal in the riser is prolonged, the feeding time is prolonged, and the metal feeding rate in the riser is greatly increased.

Description

Technical field [0001] The present invention relates to the field of solid waste resource utilization, in particular, to an organic silicon residue heat insulation riser and a preparation method thereof. Background technique [0002] Silicon slag refers to the residue obtained by a silicone by-product-organo silicone residue obtained by precipitation and hydrolysis. At present, the treatment method of silicon slag is mainly in grafting and incineration, which is easy to form environmental pollution, is a hazardous waste; and will cause waste of silicon and carbon resources. Therefore, resource is achieved while achieving harmless treatment of the silicone slag, which is of great significance for the promotion of green sustainable development of the organic silicone industry. [0003] At present, domestic and foreign industry has continuously improved the requirements of the quality of castings and production process. In casting production, the main function of the rushing and mou...
