Description
Technical field
High-speed steel field is the utility model is related to, more particularly, to a kind of fresh air drying oven for high speed steel wire drying.
Background technology
High speed steel wire also known as air hardening steel or high-speed steel, meaning can also harden even if cooling down in atmosphere during quenching, and very cutting edge of a knife or a sword
Profit.It is a kind of steel alloy of complicated, contains the carbide formers such as tungsten, molybdenum, chromium, vanadium.Alloying element total amount is up to 10
~25% or so.Its in the case of high-speed cutting produces high fever (about 500 DEG C) remain to keep high hardness, and HRC can be more than 60.
Here it is the most important characteristic of high-speed steel --- red hardness.And carbon tool steel is quenched and lonneal after, though at room temperature
There is very high hardness, but when temperature is higher than 200 DEG C, hardness just drastically declines, and is had dropped down to and annealed condition phase in 500 DEG C of hardness
As degree, completely lost the ability of cutting metal, which limits carbon tool steel make cutting element use.And high-speed steel
Because red hardness is good, the fatal defects of carbon tool steel are compensate for, can be used for manufacturing cutting element.
The Technology for Heating Processing of high speed steel wire is complex, it is necessary to by a series of processes such as annealing, quenching, tempering.Annealing
Purpose be eliminate stress, reduce hardness, make microscopic structure uniform, be easy to quench.Annealing temperature is generally 860~880 DEG C.Quench
Because its poor thermal conductivity is typically carried out in two stages when fiery.(in order to avoid causing big thermal stress) first is preheated at 800~850 DEG C,
Then 1220~1250 DEG C of hardening heat, rear oil cooling are heated rapidly to.Factory uses salt stove heat.Because of internal group after quenching
Knit a part of (about 30%) retained austenite of also reservation and be not converted to martensite, have impact on the performance of high-speed steel.To make remaining Austria
Family name's body changes, and further improves hardness and wearability, typically to carry out 2~3 tempering, 560 DEG C of temperature, be incubated 1 every time
Hour.
(1) method for manufacturing：Generally use electric furnace produces, and once produced high-speed steel using powder metallurgy process, and made carbonization
Thing is evenly distributed on matrix in superfine small particle, improves service life.
(2) purposes：For manufacturing various cutting elements.Such as lathe tool, drill bit, hobboing cutter, machine hacksaw blade and require high mould
Deng.
In order to ensure the product quality of high speed steel wire, the step of applicant is additionally arranged cleaning before high speed steel wire annealing, and
And dried after the cleaning, ensure surface cleaning of the high speed steel wire when entering annealing steps, avoid high speed steel wire from entering
Cause the degradation of whole high speed steel wire because being infected with impurity during annealing.For this, applicant, which has been specifically designed, is used for high-speed steel
The drying oven of drying of the silk before annealing after cleaning.
