Abstract
The present invention relates to technological lubricant technology, discloses one kind of lubricant, and is especially lubricant for hot rolled steel pipe expanding forcer. The lubricant consists of talc 40-60 wt%, graphite 5-30 wt%, sodium bicarbonate 20-40 wt%, trisodium phosphate 1-15 wt%. It has high lubricating effect, less forcer abrasion, long service life, high pipe expanding speed and other advantages.
Description
One, technical field
The invention discloses a kind of lubricant, particularly a kind of lubricant that is used for hot rolling steel pipe expanding top belongs to the technology lubricant technical field.
Two, background technology
Existing hot rolling steel pipe expanding top lubricant all is to be the product of main component with the borax, in the use, under 900-1200 ℃ high temperature, borax just softens and becomes liquid, thereby reaches lubricated purpose, its lubricant effect is poor, the expanding top adhesive is many, and very hard, not easy-clear, thereby making the steel pipe internal-surface after rolling that defectives such as backfin, pitted skin be arranged, product qualified rate is low; Moreover borax is under the impact of hot gas flow, and dust from flying causes serious environmental to pollute.
Three, summary of the invention
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, and the hot finished steel pipe top lubricant that provides a kind of high lubricating effect, expanding top not to have adhesive and no dust pollution.
For achieving the above object, the technical solution used in the present invention is: a kind of hot rolling steel pipe expanding top lubricant is characterized in that it forms 1-9mm by following substances in percentage by weight mixed preparing
2Talcum flap: 40-60%, 1-9mm
2Graphite flap: 5-30%, sodium bicarbonate: 20-40%, tertiary sodium phosphate: 1-15%.
The present invention compared with the prior art, the positively effect that has is because this lubricant is based on solid lubrication, lubricating substance adopts 1-9mm
2Flap, under the impact of hot gas flow, can not produce dust pollution, production environment is improved greatly; The smooth no adhesive of expanding top in process of production in addition, the steel pipe internal-surface after rolling does not have defectives such as backfin or pitted skin, good product quality, qualification rate height; Its high lubricating effect of while, the expanding top light abrasion, long service life, expander speed is fast, and production efficiency improves greatly.
Four, embodiment
For a better understanding of the present invention, below in conjunction with embodiment it is done further detailed elaboration.
Embodiment 1: take by weighing 50 gram 1-9mm respectively
2Foliated talc, 20 the gram 1-9mm
2Flake graphite, 25 gram sodium bicarbonates and 5 gram tertiary sodium phosphates, the mixture that obtains after it is mixed is hot rolling steel pipe expanding top lubricant finished product of the present invention.
Embodiment 2: take by weighing 60 gram 1-9mm respectively
2Foliated talc, 5 the gram 1-9mm
2Flake graphite, 20 gram sodium bicarbonates and 15 gram tertiary sodium phosphates, the mixture that obtains after it is mixed is hot rolling steel pipe expanding top lubricant finished product of the present invention.
Embodiment 3: take by weighing 40 gram 1-9mm respectively
2Foliated talc, 25 the gram 1-9mm
2Flake graphite, 30 gram sodium bicarbonates and 5 gram tertiary sodium phosphates, the mixture that obtains after it is mixed is hot rolling steel pipe expanding top lubricant finished product of the present invention.
The hot rolling steel pipe expanding top lubricant that makes with above embodiment is high lubricating effect in use; expander speed is fast; the smooth no adhesive of expanding top; roll the smooth zero defect of back steel pipe internal-surface; tube quality is good; this be because this lubricant in talcum under 900-1200 ℃ high temperature; stable performance; has good oilness; sodium bicarbonate issues estranged separating after reaction loses carbonic acid gas 270 ℃ temperature; under 318.4 ℃ temperature, promptly become liquid state; graphite composition in the lubricant is wrapped up, avoid graphite at high temperature oxidation to take place and lose lubrication, make graphite at high temperature have good lubrication; tertiary sodium phosphate in the process of expander to had the corrosion protection effect by expanding steel tube; talcum and graphite shared large percentage in lubricant is a solid lubricant, high lubricating effect; steel pipe final product quality height is simultaneously because talcum and graphite all are 1-9mm
2Flap, under the impact of hot gas flow, can not produce dust from flying, the production environment no dust pollution has overcome existingly with existing deficiency of series lubricant agent and defective fully, is a kind of comparatively ideal hot rolling steel pipe expanding top lubricant.
