Abstract
The present invention relates to a kind of stainless steel plate billet continuous casting machine Accident Handling Method, is specially：When accident occurs, stop production immediately, secondary coolingwater is added to maximum, fast cooling board base；Then crystallizer and zero section are hung out, with oxygen cut 1 section of top, while with oxygen cut 7 sections and 8 sections between position, cutting terminate after, crystallizer and the direct handling of more than 0 section of slab are walked, and 7 sections of later slabs are directly transported from roller-way；Dummy bar is sent into 8 sections of fan-shaped section place, the pressure clamping device of partial sector section is opened, by slab to sending dummy ingot direction to release 67 meters, then depresses all clamping devices, carry out oxygen cutting, is cut and is finished the direct handling of slab that will be cut away and walk；In incident processing procedure, the slab being frozen in continuous casting machine fan-shaped segment is cut into 4 sections, saves time and skill.
Description
Technical field
The present invention relates to stainless steel smelting field, more particularly to a kind of stainless steel plate billet continuous casting machine Accident Handling Method.
Background technology
Stainless steel smelting needs to use slab caster, as shown in the Chinese patent of Application No. 201420687266.3.
Stainless steel plate billet continuous casting machine in process of production, due to operational error or outside power failure suddenly, causes stainless steel slab to be frozen in
In the fan-shaped section of conticaster, when handling this accident in the past, the slab freezed is directly cut into the fritter of 1-2 rice with oxygen,
One piece one piece hangs out, and wastes time and energy, processing time is more than 24 hours.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and provide a kind of reasonable in design, time saving
Labour-saving stainless steel plate billet continuous casting machine Accident Handling Method.
Technical scheme is used by the present invention solves the above problems：A kind of stainless steel plate billet continuous casting machine accident treatment side
Method, it is specially：
（1）When accident occurs, stop production immediately, secondary coolingwater is added to maximum, fast cooling board base；
（2）Then crystallizer and zero section are hung out, cuts 1 section of top with oxygen, while cut between 7 sections and 8 sections with oxygen
Position, after cutting terminates, crystallizer and the direct handling of more than 0 section of slab are walked, and 7 sections of later slabs are directly transported from roller-way
Go out；
（3）Dummy bar is sent into 8 sections of fan-shaped section place, the pressure clamping device of opening partial sector section, by slab to sending dummy ingot side
To release 6-7 rice, then all clamping devices are depressed, carry out oxygen cutting, cutting finishes the direct handling of slab that will be cut away and walked；
（4）All pressure clamping devices are opened again, are all released remaining slab with dummy bar, direct handling is walked；
（5）Cleaning stainless steel plate billet continuous casting machine；（6）0 section of installation and crystallizer, accident treatment finish, and re-start production.
Preferably, in incident processing procedure, the slab being frozen in continuous casting machine fan-shaped segment is cut into after 4 sections, 7 sections
Slab directly transported from roller-way, 3 sections need handling to walk in addition.
Preferably, needing to use special handling chain during handling slab, the weight capacity of handling chain is 20
It is more than ton.
Preferably, needing to set special protection device to protect 1 section of fan-shaped section during oxygen cuts slab, avoid
Conticaster damages.
The present invention compared with prior art, has advantages below and effect：The stainless steel plate billet continuous casting machine accident treatment side
Method, the time of conticaster accident treatment can be greatly shortened, effectively shorten the processing time of accident, from stopping production to resuming production 6
Hour or so, use manpower and material resources sparingly, conticaster is quickly put into production.
Embodiment
Below by embodiment, the present invention is described in further detail, following examples be explanation of the invention and
The invention is not limited in following examples.
A kind of stainless steel plate billet continuous casting machine Accident Handling Method of the present embodiment, accident produce once generation, immediately stopping,
Secondary coolingwater is added to maximum simultaneously, carries out slab quick cooling；Then crystallizer and zero section are hung out, 1 is cut with oxygen
Section top, cutting walk crystallizer and the direct handling of more than 0 section of slab after terminating, then are cut with oxygen between 7 sections and 8 sections
Position, after cutting terminates, 7 sections of later slabs are directly transported from roller-way；Then dummy bar is sent at 8 sections of fan-shaped section, opened
The pressure clamping device of partial sector section, by slab to sending dummy ingot direction to release 6-7 rice, all clamping devices are then depressed,
Position carries out oxygen cutting between 7 sections and 8 sections, and cutting finishes the direct handling of slab that will be cut away and walked；Finally open all
Clamping device is depressed, is all released remaining slab with dummy bar, direct handling is walked；To stainless steel slab after treatment of mat is complete
Conticaster is cleared up；0 section and crystallizer are installed, so far accident treatment finishes, and conticaster puts into production again after the completion of cleaning.
In incident processing procedure, the slab being cooled in through secondary cooling water in continuous casting machine fan-shaped segment is cut into after 4 sections, 7 sections
Slab directly transported from roller-way, 3 sections need handling to walk in addition.
Need to use special handling chain during handling slab, the weight capacity of handling chain is more than 20 tons.
Need to set special protection device to protect 1 section of fan-shaped section during oxygen cuts slab, avoid cutting process
Conticaster is caused to damage.
Embodiment：
Due to jumping electricity suddenly, cause production system all to be paralysed, continuous casting steel billet is frozen in fan-shaped section, when accident occurs after, first will
Secondary coolingwater is added to maximum, fast cooling board base；Maintenance personal is carried out at accident using cutting tool, suspender, protection device etc.
Science and engineering is made, and crystallizer and 0 section are hung out, cut on 1 section of top with oxygen, the direct handling of more than 0 section of slab is walked, while
Cut with oxygen between 7 sections and 8 sections, after cutting terminates, 7 sections of later slabs are directly transported from roller-way；Then by dummy bar
It is sent at 8 sections of fan-shaped section, opens the pressure clamping device of partial sector section, by slab to sending dummy ingot direction to release 6-7 rice, depresses
All clamping devices, position is cut between 7 sections and 8 sections, after cutting direct handling walk；Finally open all
Clamping device is depressed, is all released remaining slab with dummy bar, direct handling is walked；Clear up conticaster, 0 section of installation and crystallization
Device, accident treatment finish, and conticaster puts into production；Accident treatment total time is 5.5 hours.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, its position cut, cutting equipment
Can be different.The equivalent or simple change that technique and principle described in Fan Yiben technological process inventional ideas are done, is included in
