Abstract
The invention discloses a casting method of a lining plate of a ball mill, which comprises the following steps of: A, material selection: selecting an austenite-bainite steel material; B, vacuum sealed molding; C, pouring under negative pressure: pouring at a vacuum negative pressure of 0.05-0.06 Mpa, and carrying out cancel the vacuum, sand falling and cleaning after cooling; and D, thermal treatment: adopting an electronic tempering furnace to heat to a temperature of 900-950 DEG C, keeping for 6 hours, then taking out of the furnace and putting into cooling liquid till cooling to obtain a casting to be processed. Compared with a common casting method, the produced lining plate of the ball mill has the advantages of abrasion resistance, good impact resistance, high strength and toughness and low cost.
Description
Technical field
The present invention relates to a kind of ball mill component manufacturing method, specifically is a kind of ball grinding machine lining board casting method.
Background technology
Ball grinding machine lining board is to be used for protecting cylindrical shell; Make cylindrical shell avoid abrasive body and directly impact and friction of material; Multi-form liner plate also capable of using is adjusted the motion state of abrasive body simultaneously, to strengthen abrasive body to the material grinding effect, helps to improve the mill efficiency of grinding machine; Increase output, reduce metal consumption.
It is wear-resisting for the ball grinding machine lining board that the conventional cast method is produced, impact resistance is relatively poor, and intensity, toughness are not high, and cost is too high.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of ball grinding machine lining board casting method, becomes originally low, has than high-wearing feature and intensity.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of ball grinding machine lining board casting method, may further comprise the steps,
A selects materials: the material of selecting austenite-bainite steel for use;
B vacuum seal modeling;
B1 cover mold: adopt plastic sheeting sealing sandbox;
B2 molding: with air in the vacuum air pump extraction type, pressure differential is arranged inside and outside the casting mold, make dry sand closely knit, form required die cavity, accomplish a casting mold;
B3 mould assembling cast: core under the ceramic mould is adopted at the position at the descending core of needs, chill under the position of chill under needs, and the sandbox that closes then forms the casting mold that dead head and die cavity are arranged, and places cup, accomplishes whole modeling;
C vacuum-assist pouring: cast under the state that vacuumizes negative pressure 0.05Mpa-0.06Mpa, cooling back cancellation vacuum, knockout, cleaning;
D heat treatment: adopt electronics tempering kiln, be heated to 900-950 ℃, kept 6 hours, coming out of the stove then is placed in the cooling fluid until cooling, obtains foundry goods to be processed.
The present invention compares, and it is wear-resisting, impact resistance good for ball grinding machine lining board that the conventional cast method produces, and intensity, toughness are high, and cost is low.
