Definitions
- the coating acts as a lubricant and may be applied a second, or other times, after completing several ingots.
- the present invention relates to methods of running in the working Walls of a mold.
- An object of the present invention is to develop a method of running in the working walls of a mold which accelerates the running-in process.
- An important object of the present invention is to develop a method of running in the working walls of a mold, which is simple to realize.
- a further object of the present invention is to develop a method of running in the working walls of the mold which improves the quality of the ingot being cast.
- the coating is a lubricant based on polymers with the additions of molybdenum disulphide.
- Said lubricant may be applied upon the mould Working walls repeatedly after completing a number of casts.
- the method of running in the working walls of the mold consists in preparing new or repaired working walls 3,447,588 Patented June 3, 1969 of the mold by thoroughly cleaning them from oxides and degreasing them by acetone or ethyl alcohol.
- the surfaces of the working walls of the mold thus prepared are covered, by the aid of a spray or by any other existing method, with a thin even coating of a lubricant in the form of polymers with additions of molybdenum disulphide.
- the polymer base is composed of an epoxy resin.
- This lubricant is prepared in the following manner.
- the working Walls of the mold are dried for a period not less than one day.
- the surfaces of the working walls of the mold are washed by kerosene, dried, and the lubricant is applied thereon for the second time.
- molybdenum disulphide which partially diffuses into the working walls and remains on their surfaces, forms a surface layer which decreases the friction and prevents the adherence of the solidifying metal.
- the lubricant When the lubricant is applied for the second time, it can be employed without the use of epoxy resin, additions of dibutyl phthalate and polyethylene-polyamine.
- the method of running in the working faces of the mold described above is capable of speeding up the running-in process, is simple to be realized, and decreases the forces required for extracting the ingot from the mold by as much as 1.5 times.
- a method of running in the working walls of a mold in the process of continuous casting of metal by first applying thereon a lubricant on the basis of a polymer with additions of molybdenum disulphide.
