Considerations for selecting cored wire equipment
In order to improve the quality of steel and to enable the ladle and refining furnace to achieve the objectives of desulphurisation, deoxidation, fine tuning of the composition and breeding, operators are required to feed alloy cored wire and aluminium wire into the ladle (molten iron ladle) through the cored wire equipment during the steel refining process. In the metallurgical industry, as the steelmaking process continues to develop, the demand for high quality alloy steel, bearing steel and varieties of steel is increasing, and the cored wire equipment process has a greater yield than the traditional powder spraying method. Customers need to master the following common sense and skills when purchasing cored wire equipment.
First, the first need to confirm the number of core wire and parameters: the product model is a double stream or four streams, more consultation to examine the quotation of several core wire manufacturers, the ability to feed the wire, service life and wear parts material and after-sales service commitment.
Second, the quality of the core wire identification methods: first look at the appearance of the equipment, paint treatment and outer cover of the colour is new. Secondly, according to the operation manual to test the machine to ensure that all parts of the equipment can operate normally and whether there is noise.
Third, maintenance and after-sales service commitment: due to the use of cored wire position is relatively special so after the failure, cored wire equipment manufacturers after-sales is particularly important, the general time promised by the manufacturer is 48 hours to the scene to deal with the problem, but really can do not much. This will need to sign a contract to set aside a portion of the warranty to ensure that after-sales service and commitment to timely delivery.
