Description

A kind of high speed steel wire circulated air drying oven
Technical field
The present invention relates to high-speed steel field, more particularly, to a kind of high speed steel wire circulated air drying oven.
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.
The content of the invention
Problem to be solved by this invention is, for it is above-mentioned in the prior art the shortcomings that, propose improvement project or replacement Scheme, it is especially a kind of to improve high-speed steel product quality, ensure improvement or the alternative of H.S.S. production qualification rate.
To solve the above problems, the scheme that the present invention uses is as follows:A kind of high speed steel wire circulated air drying oven, its feature exist In, including chassis and drying furnace body, it is described drying furnace body be arranged on chassis;The drying furnace body is by shell, inner bag Formed with furnace lining;The top of the drying chamber is provided with air channel, and the air channel is provided with multiple nozzles towards the one side of drying chamber;It is described Inner bag is arranged on the inside of shell;The furnace lining is arranged between shell and inner bag;The top of the drying furnace body, which is provided with, to be added Hot tank and blower fan;The blower fan is provided with blast pipe and discharge pipe, one end UNICOM of the blast pipe and drying chamber, the discharge pipe With air channel UNICOM, circulated air is formed between the blower fan, discharge pipe, air channel, nozzle, drying chamber and blast pipe;The heater box It is arranged on the discharge pipe of blower fan;Front and rear fire door is arranged with the inner bag and shell at the drying chamber both ends.
Further, the high speed steel wire circulated air drying oven according to above-mentioned design, it is characterised in that the drying chamber The one end being connected with discharge pipe offers rear fire door, the outlet after being dried as high speed steel wire;The drying chamber connects with blast pipe The one end connect offers preceding fire door, the import as high speed steel wire drying.
Further, the high speed steel wire circulated air drying oven according to above-mentioned design, it is characterised in that the blast pipe One layer of heat preservation layer is coated with the outside of discharge pipe.
Further, the high speed steel wire circulated air drying oven according to above-mentioned design, it is characterised in that on the chassis A dividing wire frame is respectively provided with the outside of front and rear fire door;The dividing wire frame includes support frame and roller;The roller passes through axle It is arranged on support frame, support frame as described above is fixedly installed on chassis, and the roller is provided with groove, for support high-speed steel Silk, the bottom surface of the groove of the roller most significant end are slightly above the bottom surface of front and rear fire door.
Further, the high speed steel wire circulated air drying oven according to above-mentioned design, it is characterised in that on the shell A drying oven check apron is respectively provided with front and rear fire door.
Further, the high speed steel wire circulated air drying oven according to above-mentioned design, it is characterised in that the blast pipe It is provided with filtering, dehumidifying device.
The technique effect of the present invention is as follows:The high speed steel wire circulated air drying oven of the application is mainly used in high speed steel wire and entered Enter the drying after cleaning treatment before annealing steps, its starting point of the high speed steel wire circulated air drying oven of the application is to improve height The product quality of fast steel wire, therefore particularly it is additionally arranged cleaning process before high speed steel wire annealing steps.When high speed steel wire passes through A little moisture, therefore the special high speed steel wire circulated air drying oven for devising the application are speckled with after cleaning process, on high speed steel wire.
The high speed steel wire circulated air drying oven of the application provides power using blower fan, in blower fan, blast pipe, discharge pipe, baking A circulated air is formd between dry chamber, and heater box is provided with discharge pipe, is heated using heater box for circulated air, most End form is into a thermal cycle wind.High speed steel wire enters drying chamber from preceding fire door, by being gone out after drying chamber from rear fire door, high-speed steel The direction of motion of the direction of motion and thermal cycle wind of silk in drying chamber is opposite.In order to farthest ensure that high speed steel wire passes through The drying crossed after high speed steel wire circulated air drying oven, especially by the top design of drying oven into air channel, and in air channel towards baking Dry stove side sets multiple nozzles, and stream of hot air is formed using nozzle, and High Temperature Gas is carried out to the high speed steel wire entered in drying chamber Stream injection drying.The high-speed and high-temperature airflow formed using nozzle accelerates the drying of high speed steel wire.
