The cooling-water duct of existing contact element all is to form with machining after the moulding, because the draw ratio in hole is excessive, causes difficulty to processing, and it is crooked or penetrate the problem of tube wall that water channel often takes place, and the percent defective high efficiency is low, and processing cost is high.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, provide a kind of simple in structure, simple for production, processed finished products rate height, the ore deposit that cost is low hot stove conduction contact element.
Another object of the present invention provides the manufacture method of the hot stove conduction in above-mentioned ore deposit with contact element.
The technical scheme of taking for achieving the above object is:
A kind of ore deposit hot stove conduction contact element, it is characterized in that: comprise that the left element and the right element that adopt symmetrical structure are combined into the contact element body, described left element is connected by coupling assembling with right element and adjusts, and is provided with between the element of the left and right sides for the muscle sheet that imports electric current to graphite electrode.
Be respectively equipped with intake tunnel and exhalant canal in above-mentioned left element and the right element, described intake tunnel and exhalant canal are to be two elongated circular holes that are parallel to contact element body length direction, its diameter and length ratio reach 1:30, and two passage terminations are communicated with by horizontal circular hole, and shape takes the shape of the letter U.
Described left element and right element adopt casting method to cast out, and wherein intake tunnel and exhalant canal are to be formed by core.
The hot stove conduction in the above-mentioned ore deposit manufacture method of contact element is characterized in that its technical process is:
A. according to the shape modeling of left element or right element;
B. model is put into sandbox, filling moulding is placed in prefabricated core within the die cavity behind the taking-up model;
C. left sandbox and right sandbox are integrated, put into and vacuumize sandbox, sandbox top covered with plastic film, sealing sandbox slit starts vacuum system with the air emptying in the sandbox;
D. vacuumize again under the state, liquid metals is entered die cavity by running gate system;
E. liquid metals is full of die cavity, and vacuum system works on, and solidifies casting forming up to liquid metals.
The present invention utilizes casting method that contact element is cast out, during manufacturing a plurality of contact elements are arranged in the same sandbox, utilize entery and delivery port as venthole and clearance hole, the water-in and water-out passage is formed by core, core print plays a part to shake out and gives vent to anger, and also plays supporting and the fixedly effect of core of uniting with core print.The present invention utilizes casting method that the inner circular elongated cooling-water duct that distributes of contact element is cast out, saved the machining operation, overcome the bigger problem of processing slim circular hole difficulty, not only shortened the process-cycle but also guaranteed product quality, and manufacture method is easy, easy, processed finished products rate height, cost is low.

The specific embodiment
A kind of ore deposit hot stove conducting system contact element, comprise the left element 3 of an employing symmetrical structure and the contact element body that right element 8 combines, be respectively equipped with intake tunnel 4 and exhalant canal 6 in described left element 3 and the right element 6, described intake tunnel 4 and exhalant canal 6 are two elongated circular holes that are parallel to contact element body length direction, its diameter and length ratio reach 1:30, two passage terminations are communicated with by horizontal circular hole 7, the shape that takes the shape of the letter U, the other end is connected with water inlet 10 and delivery port 11 respectively.Contact element needs the water flowing cooling in use, and cooling water is flowed into by water inlet 10, is flowed out by delivery port 11 by cooling-water duct.Described left element 3 is connected by coupling assembling 5 with right element 8 and adjusts, and makes that equally distributed muscle sheet 9 is clamped between the element of the left and right sides on the electrode shell 2.Some windings are touched element and are distributed in around the graphite electrode 1, import electric current by muscle sheet 9 to graphite electrode, if graphite electrode is applied external force carries out lifting, muscle sheet and contact element then slide up and down along the gap, and reaching does not have a power failure just can adjust to electrode the effect of correct position.
