Abstract
The invention relates to powder manufacturing equipment and especially relates to a screw rod for a mixing mill of the powder manufacturing equipment. A high-abrasion-resistance tungsten carbide coating is coated on the surface of the screw rod of a spindle; the tungsten carbide coating is coated according to a hypersonic flame spraying method; and the carbonized thickness is about 0.2-0.3mm. The surface hardness is increased; the probability of impact crushing is increased; the abrasion is reduced; the crushing efficiency is increased; the equipment maintenance cost is lowered; and the service life of the equipment is prolonged.
Description
Technical field
The present invention relates to the powder manufacturing equipment, particularly a kind of mixing roll screw rod for the powder manufacturing equipment.
Background technology
In the mixing and crushing process of powder processing, the surface temperature of mixing roll screw rod and powder is very high, the long-term continuous operation mixing roll screw rod that is easy to wear and tear, and this case hardness to the mixing roll screw rod has high requirements.Most domestic mixing roll screw rod adopts the nitrogen treatment technology to improve case hardness.Powder for ultra-fine grain, because its particle diameter is very little, when pulverizing, require the headscrew High Rotation Speed, drive the powder high-speed motion, the high-speed motion of powder forms huge repeated stock to screw surface, accelerates the screw surface wearing and tearing, use the screw rod of nitrogen treatment can not meet the demands, need frequent stopping production repair and replacement, not only impact is produced, and also will increase maintenance cost.
Summary of the invention
The problem that the present invention solves is to provide a kind of mixing roll screw rod for the powder manufacturing equipment, in the tungsten carbide of its surface coating one deck high abrasion, raising case hardness, the service life of extension device.
For achieving the above object, technical scheme of the present invention is: a kind of mixing roll screw rod for the powder manufacturing equipment, comprise headscrew, and adopt method coating one deck high abrasion carbonization tungsten coating of HVAF on the surface of headscrew; Step is as follows: be that the screw rod of 38CrMoAl chrome molybdenum aluminium Vickers hardness Hv750 carries out blasting treatment to material at first, improve surface adhesion force; Then adopt the method for HVAF, at screw surface coating one deck tungsten carbide coating, the thickness of tungsten carbide coating (2) is 0.2-0.3mm.
The invention has the beneficial effects as follows: 1. owing to adopting tungsten carbide coating to improve case hardness, reduced wearing and tearing, screw rod obviously improves service life, has reduced the maintenance of equipment cost; 2. because machined is not carried out on the tungsten carbide coating surface, and the surface is the sand face, slightly degree of making is higher, has improved crush efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of mixing roll screw rod for the powder manufacturing equipment, as shown in Figure 1: be that the screw rod of 38 chrome molybdenum aluminium (38CrMoAl) Vickers hardness Hv750 carries out blasting treatment to material at first, improve surface adhesion force, then adopt the method for HVAF, at screw surface coating one deck tungsten carbide coating, coating layer thickness 0.2-0.3mm.
Claims (2)
1. a mixing roll screw rod that is used for the powder manufacturing equipment comprises headscrew (1), it is characterized in that: the method coating one deck high abrasion carbonization tungsten coating (2) that adopts HVAF on the surface of headscrew (1); Step is as follows: be that the screw rod of 38CrMoAl chrome molybdenum aluminium Vickers hardness Hv750 carries out blasting treatment to material at first, improve surface adhesion force; Then adopt the method for HVAF, at screw surface coating one deck tungsten carbide coating.
2. a kind of mixing roll screw rod for the powder manufacturing equipment as claimed in claim 1, it is characterized in that: the thickness of described tungsten carbide coating (2) is 0.2-0.3mm.
