Description

A kind of double end depassing unit

Technical field

The utility model is related to a kind of depassing unit, more particularly, to a kind of double end depassing unit.

Background technology

Known, during non-ferrous metals casting, the number containing gas directly influences the quality of casting in aluminium liquid, Degassing procedure is mainly the gas removed in aluminium liquid, prevents casting from producing stomata and slag inclusion；Generally cast aluminium stomata is useless Product rate accounts for the 30% ~ 75% of percent defective summation, greatly reduces the requirement of quality and yield, so using good degassing unit to carrying High-quality and yield is vital, and the degasification lever apparatus that the current 400KG of in the market smelting furnace is used is single pole device, single tube Main use is silicon carbide material, and its shortcoming is：

1. use cost is high；

2. degassing effect is poor：Because degasification head only one of which and direction downwards, degasification is uneven, cause portion gas and Residue can not be discharged；

3. it is fragile：Because its material is carborundum, attribute is very crisp, and not noting slightly in production will fracture damage；

4. baking time is long, productive temp is influenceed：Need the dress degasification bar used to put before production and application and be baked to 500 It could be used more than DEG C, because its material is carborundum, dryness water is contained in the inside, and baking time is about needed 3-5 days, extreme influence life Beat.

The content of the invention

In order to overcome the shortcomings of in background technology, the utility model discloses a kind of double end depassing unit, by steel pipe Outside be provided with heat-insulation layer, be equipped with heat insulating block in the outer end of transverse pipe, realize degasification, remove the gred, reduce cost purpose.

In order to realize the goal of the invention, the utility model is adopted the following technical scheme that：

A kind of double end depassing unit, including steel pipe and heat-insulation layer, heat-insulation layer is provided with the outside of steel pipe, close to steel pipe one The transverse pipe that connection is set is fixed with the two sides for holding end, heat insulating block, the insulation are equipped with the outer end of transverse pipe Block is the conical section that outer diameter is small, inner diameter is big.

Described double end depassing unit, the heat-insulation layer is refractory material, and the refractory material is fireproof line, and fireproof line is twined It is wound on the outside of steel pipe.

Described double end depassing unit, the steel pipe and transverse pipe are seamless steel pipe.

By adopting the above-described technical solution, the utility model has the advantages that：

Double end depassing unit described in the utility model, by the outside winding fireproof line in the steel pipe being welded, in horizontal stroke Heat insulating block is installed to the both ends of the transverse pipe of setting, the shape outer end of heat insulating block is small inner big, plays and protects steel pipe not by aluminium Aqueous corrosion is scorched, is incubated, and can uniformly be vented the effect for reaching degasification, and double end depassing unit can make gas directly from pot wall Center is directly returned to, can discharge residual gas and residue, degasification, slagging-off purpose are reached with this；The utility model is practical Property it is strong, be hardly damaged, install and use all fairly simple, not only reduce cost, reduce percent defective, greatly improve Production efficiency and operating efficiency.

Embodiment

Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protection All technological improvements in the range of the utility model.

Double end depassing unit with reference to described in accompanying drawing 1-2, including steel pipe 1 and heat-insulation layer 2, set in the outside of seamless steel pipe 1 There is heat-insulation layer 2, the transverse pipe that connection is set is being fixed with the two sides of one end end of steel pipe 1, in the outer end of transverse pipe Portion is equipped with heat insulating block 3, and the heat insulating block 3 is the small conical section of big, the inner diameter of outer diameter；The heat-insulation layer 2 is fire resisting Material, the refractory material is fireproof line, and fireproof line is wrapped in the outside of steel pipe 1；The steel pipe 1 and transverse pipe are seamless steel Pipe.

Implement double end depassing unit described in the utility model, when in use, first pass through vertical steel pipe 1 to wind fire resisting Rope, can sufficiently protect vertical seamless steel pipe, prevent vertical seamless steel pipe from damaging, and increase service life；The horizontal stroke of two transverse directions Heat insulating block is installed on to pipe, two horizontal seamless steel pipes can be sufficiently protected, prevents that laterally two seamless steel pipes are damaged, plus Big service life；, can be effective actual in use, the utility model can make gas directly return to central core from pot wall Take gas and residue out of.

The non-detailed portion of the utility model is prior art.

The embodiment selected herein to disclose goal of the invention of the present utility model, is presently considered to be suitable, However, it should be understood that, the utility model is intended to include the institute of all embodiments belonged in the range of this design and utility model Change and improve.

Claims
