Description
Technical field
The invention belongs to rising head and make field, be specifically related to a kind of production method of heat preservation riser buss.
Background technology
When common riser buss carries out feeding, required rising head volume is large, and molten metal consumption is large and utilization rate is low.Therefore, many producers application insulating riser sleeve or exothermic riser sleeve extend rising head setting time to a certain extent, improve feeding efficiency.But because common insulating riser sleeve can not provide heat to rising head, and heat preservation riser buss has self-heating heat insulation function, thus can utilize the shortcoming of rate variance from more stupid upper solution riser metal liquid.The external collection heat and insulation that adopted is applied to production with the composite casting head cover of one, but this type of research domestic is also rare.These heat preservation riser buss exothermic material formulas are had nothing in common with each other, but mostly adopt high temperature exothermic mode, can not realize fever time controlled.
Heat preservation riser buss is generally by insulation material, exothermic material, oxidant, the combination such as refractory material and alite paste is made, wherein, the heating property of selection to heat preservation riser buss of oxidant plays a decisive role, exothermic material multiselect aluminium powder and bloodstone in external heat preservation riser buss, change less, and the selection of oxidant is also not quite similar, change more, the domestic research to oxidant is less, traditional insulating riser sleeve, the feeding efficiency of the riser buss developed is lower, and production technology performance and the every serviceability of product poor, promotion material is updated, alleviate resource nervous, save energy and reduce the cost and improve the aspects such as consumer products quality and there is lower economic benefit and social benefit.
Summary of the invention
The object of the present invention is to provide a kind of production method of heat preservation riser buss, can effectively solve the problem.The present invention is achieved through the following technical solutions:
A production method for heat preservation riser buss, its elementary production steps is as follows:
A, batching: measure exothermic material, insulation material, oxidant, refractory material and alite paste, its weight ratio is 2:1:0.1:1:0.01, described exothermic material is the mixture of magnesium powder, aluminium powder and iron powder, it is 0.5:1:1 by weight, described insulation material is organic carbon, described oxidant is sylvine oxygenant, and described refractory material is silica sand;
B, mixed system: the formula materials of above-mentioned steps is mixed, first oxidant and insulation material are added mixed 3min processed in spheroidal bowl mixer, next adds exothermic material and refractory material continues mixed 1.5min processed in spherical mixed machine processed, add alite paste again and carry out mixed 1.5min processed, adopt combined multi-stage heating system, namely comprise organic carbon low-temperature heating and magnesium, aluminium, silicon high temperature exothermic, described sylvine oxygenant has composite catalyzing function;
C, moulding: use forming machine and mould, mixed material is made exothermic riser sleeve, 1-2 days is placed in demoulding cooling;
D, oven dry: will make exothermic riser sleeve and dry in baking oven or baker at a set temperature as on oven dry plate, bake out temperature is 150-160 DEG C, and drying time is 90 minutes;
E, inspection: the inspection heat preservation riser buss made being carried out to presentation quality and size quality, certified products enter packet assembler, defective recycling;
F, packaging: carry out packaging warehouse-in by packing of product standard.
Riser feeding principle: when foundry goods cools in casting mold, because volume shrinkage mass is large and trend towards forming concentrating shrinkage cavity, therefore need to compensate the liquid contraction of molten metal in die cavity and the contraction in casting solidification process with rising head, to obtain the sound casting not having shrinkage cavity.
The design principle of heat preservation riser buss: heat preservation riser buss relies on the burning of exothermic material to improve the stable of riser metal liquid, and can ensure that the duration of chemical reaction is as far as possible through whole process of setting, the heat-insulating property of insulation material is relied on to be that heat in rising head not easily sheds, thus reach prolongation rising head setting time, improve the object of riser supplement shrink efficiency.
Beneficial effect of the present invention: this project according to exothermic mixture efficiency to metal consumption in Foundry Production, yield rate, the impact of casting quality and Changing Pattern, adopt combined multi-stage heating system, namely organic carbon low-temperature heating is comprised, and magnesium, aluminium silicon high temperature exothermic, formula materials has sylvine oxygenant composite catalyzing function, the novel fire resistant developed, low heat conduction, with the heat preservation riser buss of height heating, there is fabulous thermal stability, stable up to 1600 DEG C, compared with traditional insulating riser sleeve, the feeding efficiency of the riser buss developed can significantly improve, and production technology performance and the every serviceability of product keep good, promotion material is updated, alleviate resource nervous, save energy and reduce the cost and improve consumer products quality etc. and there is distinct economic and social benefit, there are wide market prospects, adopt sequential mixing technique with adapt to the process based prediction model of use material, design the production line balance pattern that the semi-mechanization realizing accurate quantitative analysis and temperature control joins manual work, high-quality and the capacity requirements of the quality of production can be ensured, the feature that can vary in size for the riser buss of different purposes again, realize fever time controlled, and improve riser buss heating efficiency, fever time, and heating power, save cost of investment.
