Description

A kind of electroslag remelting pretreatment unit

Technical field

The utility model relates to a kind of electroslag remelting pretreatment units.

Background technique

Electroslag remelting is completed to obtain the high performance alloy material such as superior alloy steel, high-temperature alloy steel and by smelting Steel carries out the refinery practice of secondary remelting by slag resistance heat.Electroslag used the dry slag starting the arc in the past, i.e., crystallizes in copper water cooling Electroslag melting is carried out after dry slag is directly fused into liquid slag in device.This technique can bring two problems：1. the dry slag starting the arc can make At ESR ingot bottom cinder inclusion, the quality of ESR ingot bottom is influenced, needs to saw the material of ESR ingot bottom 100mm or so after remelting Fall, reduce lumber recovery, also implies that and increase production cost.2. and adopt this method carry out starting the arc slugging can be to copper water The copper soleplate of cooling crystallizer causes to be easily damaged copper soleplate compared with macrolesion, reduces the service life of copper soleplate, causes production cost It increases.

Summary of the invention

The purpose of this utility model is that, in the prior art, the dry slag starting the arc, which generates cinder inclusion, to be influenced product quality and do The problem of slag starting the arc reduction crystallizer copper bottom plate service life, provides a kind of electroslag remelting pretreatment unit.

The purpose of this utility model is achieved through the following technical solutions：

A kind of electroslag remelting pretreatment unit, including vessel, vessel bottom, which is closed, upper end is opening-like sets It sets；

Metal shell is coated outside vessel, the inner surface of metal shell and the outer surface of vessel match, Metal shell and vessel fastening are in integral structure；

It further include that device is lifted at end, end is lifted device and is fixed on metal shell；

It includes that handle and fork handle are lifted in end that device is lifted at end, and it is in elongated rod shape that handle is lifted at end, and end is lifted handle one end and is arranged in container sheet On body, the other end is connect with fork handle；

It includes engaging lug that device is lifted at end, and engaging lug, which is arc-shaped, to be fixed on vessel outer wall, and end is lifted handle and set It sets on engaging lug；

It is respectively arranged with end on two opposite side walls of metal shell and lifts device.

Using a kind of electroslag remelting pretreatment unit provided by the utility model, using machining graphite at bottom closing, on The vessel of end opening, vessel inner cavity make solid slag charge in crystal vessel ontology for containing slag charge by electrode Interior melting is in a liquid state, then liquid slag charge is poured into copper water mold.After the pretreatment unit, ESR ingot bottom packet Slag degree greatly reduces, and improves ESR ingot bottom surface quality, improves ESR ingot lumber recovery.It is small to copper soleplate damage simultaneously, prolong Copper sheet service life has been grown, has been reduced costs.

Specific embodiment

The utility model is further described through combined with specific embodiments below：

As shown in Figure 1 to Figure 2, a kind of electroslag remelting pretreatment unit provided by the utility model, which includes by protecting The vessel 1 that warm heat proof material is constituted, the bottom closing of vessel 1, upper end opening is in tubbiness.The inner cavity of vessel 1 For containing electroslag slag charge.Solid-state electroslag slag charge is melted into liquid since the device needs to be heated at high temperature, so thermal insulation material The performance of high temperature resistant and conduction is also needed, so thermal insulation material is preferably graphite, and graphite also has quality is softer to be easy to add The features such as work and stable chemical performance.To protect crystal vessel ontology, avoid causing vessel to damage because colliding with, in graphite The outer layer of vessel preferably coats one layer of metal shell 2, and the inner wall of metal shell 2 is tightly attached to the outer wall of crystal vessel ontology On, the fastening of crystal vessel ontology 1 of metal shell and internal layer is in one to prevent metal shell from falling off.Metal shell selection is common Carbon steel sheet.Preferentially, it is lifted for convenience of end, end can be set on metal shell and lift device, end is lifted device and preferably grown The handle of rod, the handle of long rod include that handle 4 and fork are lifted 5 in end, and end act handle portion is preferably pipe fitting or bar, by Higher temperature is had after the thawing of electroslag slag charge, will affect the normal operating of worker when the device is lifted at end, so handle is most Good setting is in long rod type, and when such worker operation can be slightly remote from crystal vessel ontology.One end that handle 4 is lifted at end can be straight It connects and connect and can also be connected by engaging lug 3 with metal shell 2.Engaging lug 3, which can be set, to be arc-shaped, and fixation is set circular arc outward It sets on metal shell.One end that handle 4 is lifted at end is fixed in the arc-shaped surface of engaging lug 3, can be increased end in this way and be lifted handle 4 With the connection area of metal shell 2, prevents use process middle-end from lifting handle 4 and be broken from the junction of metal shell 2.Preferentially, The free end that handle 4 is lifted at end is arranged in 5 in fork, and fork can be set 5 and U-shaped be transported with facilitating worker's both hands end to lift the device It send and topples over.

Due to using manual operation in operation, and to consider service life, so crystal vessel ontology will be of moderate size, It is not easy overweight.The thickness of crystal vessel ontology is advisable in 40mm ~ 50mm or so.Equally, the thickness of metal shell 2 and the device Size matches, and should guarantee that the external intensity of the device not can increase unnecessary weight again, metal shell selects steel plate Thickness is advisable with 3mm ~ 5mm.

Such crystal vessel is suitable for weight in 4 tons of electroslag remeltings below, when being related to the biggish electroslag remelting of weight, then It needs to utilize boom hoisting.
