Abstract
The invention relates to an easy-cutting ceramic runner tube and a preparation technology. The runner tube is sintered from the following materials, by weight, potter's clay or/and clay 81-89%, a bauxite clinker 8-11% and a loosening agent capable of combustion in a process of sintering 3-8%. The preparation technology is : grinding all materials to meet required granularities; mixing the grinded materials; adding water and stirring; moulding by a machine; and sintering after drying, wherein the sintering temperature is 1100 plus or minus 50 DEG C, and the sintering time is 14-16 hours. The technology provided in the invention improves moulding efficiency of casting and reduces production cost.
Description
Technical field
The invention belongs to a kind of technical field of refractory materials, particularly a kind of improvement that is used for the pouring channel tube that metal casting process molten steel passes through.
Background technology
Pottery pouring channel tube (having another name called refractory tube, gate pin) is used to provide the molten steel of thawing to flow into the passage of casting mould in the metal casting process.Generally all adopt potter's clay or clay to fire and form, because the material that passes through is a high temperature hyperbaric solution body, not only need be high temperature resistant, but also need proof strength, in order to reduce the resistance that steel flow is crossed, internal surface needs smooth densification.Therefore, the sector all adopts high-density, high-intensity ceramic structure for guaranteeing the gate pin quality.In Foundry Production reality,, all different to length, the angle requirement of earthen-ware pipe because foundry goods moulding shape style is various; Need at the scene earthen-ware pipe to be cut so that cooperate installation, like this, high-density, high-intensity ceramic pouring channel tube cut just pretty troublesome; Not only need adopt the diamond cutting blade to add the water cutting causes cost too high; Beyond the length consuming time, also need clean once more and dry after the cutting, delayed the moulding production schedule greatly.
Summary of the invention
The object of the invention provides a kind of easy Cutting Ceramics pouring channel tube, to improve casting and molding efficient, reduces production costs.
Specifically; Technical scheme of the present invention is following: be prone to the Cutting Ceramics pouring channel tube, it is to adopt the material sintering of following weight percent to form: potter's clay is or/and clay 81-89%, bauxitic clay grog 8-11%; Combustible raising agent 3-8% in the sintering process, each component adds up to 100%.
Said raising agent is one or more mixtures in sawdust, wood chip or the coal dust.
The preparation technology of above-mentioned easy Cutting Ceramics pouring channel tube is: the belongings abrasive lapping adds water and stirs to requiring granularity to mix, machine-processed moulding, and oven dry back sintering, sintering temperature is: 1100 ± 50 ℃, sintering time is: 14-16 hour.
The present invention is owing to added combustible raising agent in the sintering process in prescription, through sintering, raising agent burning back forms uniform pore at finished product earthen-ware pipe pars intramuralis; These pores can not influence the speed that molten steel passes through in the castingprocesses because the aperture is minimum, can not cause yet and wash away and seepage; Under the prerequisite that guarantees castability, this earthen-ware pipe possesses the characteristic that adopts the ordinary resin emery wheel to cut, and cutting process need not to add water; Cutting speed in feet per minute is exceedingly fast, the cutting facility less investment, and no longer need sintering after the cutting; Can directly construct, improve operating efficiency greatly, reduce production cost.And all there is outfit at plain wheel cutting machine moulding scene, is used for cutting metal material at ordinary times, need not newly added equipment.This law is named as gate spool and is particularly useful for the resin sand casting iron craft.
