Abstract
The invention discloses a bentonite lubricant which is characterized by being prepared by mixing the following raw materials in percentage by weight: 1%-40% of bentonite, 0%-20% of talcum powder, 0.5%-5% of barium stearate, 0.1%-5% of polyacrylamide, 0%-10% of polyethylene glycol, 2%-30% of sodium hexametaphosphate, 1%-15% of calcium metaborate and the balance of water. The bentonite lubricant disclosed by the invention is a safe and environmental-friendly high-temperature lubricant and can be used for prolonging the service life of a core rod. In the high-temperature using process of the bentonite lubricant, a part of components of the bentonite lubricant are in a melting state and form a liquid film on the surface of a powder material, so that the friction between the outer surface of the core rod and the inner surface of a steel pipe is reduced, and the service life of the core rod is prolonged. The bentonite lubricant disclosed by the invention has good lubricating property under the condition of high-temperature rolling at 1000-1200 DEG C. In general case, the average service life of the core rod is 2000-3000 when a graphite lubricant is used, and the service life of the core rod is more than 3000 when the bentonite lubricant is used.
Description
Technical field
The present invention relates to a kind of wilkinite lubricant for hot rolled seamless steel tube.
Background technology
In process of metal working, solid lubricant is adsorbed onto metallic surface and forms composite lubricating film in its mutual moving process, the metal to-metal contact between contact material is become the friction between lubricant film and the transfer film transferring to material surface, thus significantly reduces frictional wear.Bentonitic thixotropy has the effect of rheology modifier in the lubricant, has excellent oilness, thermotolerance, at high temperature not drip, is the lubricant that on heavy (merchant) mill, requisite high-temperature high-load is outstanding.But lubricant prepared by existing use wilkinite is high temperature resistant, high loading is poor.
Summary of the invention
Technical problem to be solved by this invention is the problems referred to above existing for lubricant prepared for existing wilkinite and the wilkinite lubricant providing a kind of high-temperature high-load outstanding.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
Wilkinite lubricant, is characterized in that, forms by following weight percent mixed raw material is standby:
Owing to have employed technique scheme, the present invention is a kind of safety, environment-friendly high-temperature lubricant, improves the work-ing life of plug.This lubricant is in applied at elevated temperature process, and the constituent part in lubricant is in molten state, forms one deck liquid film on the surface of powder, reduces mandrel outer surface and the friction of steel pipe internal-surface, extends the work-ing life of plug.
Wilkinite lubricant of the present invention is under 1000 ~ 1200 DEG C of high temperature rolling conditions, lubricity is good, generally, when using oildag, the mean life of plug is that 2000-3000 props up, and uses be more than 3000 work-ing life during bentonite base lubricant.

Comparative example 1
Wilkinite lubricant, forms by following weight percent mixed raw material is standby: wilkinite 35%, barium stearate 1%, polyacrylamide 0.3%, polyoxyethylene glycol 6%, Sodium hexametaphosphate 99 8%, calcium metaborate 8%, water surplus.
The liquid oxidation-resistant film of mixture high temperature happy and harmonious rear generation one deck densification of said components, but its mobility and lubricity poor.
Comparative example 2
Wilkinite lubricant, forms by following weight percent mixed raw material is standby: wilkinite 5%, talcum powder 20%, lithium stearate 3%, polyacrylamide 0.5%, polyoxyethylene glycol 6%, Sodium hexametaphosphate 99 6%, calcium metaborate 8%, water surplus.
A kind of liquid inert oxide film is generated after above-mentioned solid mixture melting, this mixture has certain mobility in the molten state, but its film forming is uneven, cannot meet tube rolling requirement.
Comparative example 3
Wilkinite lubricant, forms by following weight percent mixed raw material is standby: wilkinite 15%, talcum powder 10%, barium stearate 2%, sodium polyacrylate 0.5%, polyoxyethylene glycol 6%, Sodium hexametaphosphate 99 6%, calcium metaborate 8%, water surplus.
After said components solid mixture fully mixes with water, generate one deck liquid inert oxide film in the molten state, its lubricity meets tube rolling requirement substantially, but mobility is comparatively large, and film forming is thinner, is unfavorable for tube rolling condition under high loading.
