Over­view

Today, steel is one of the most im­port­ant in­dus­trial ma­ter­i­als. The steel in­dustry sup­plies in­ter­me­di­ate products, such as hot wide strips, for­ging parts, sheet metal, rails, long products, wire and pipes, which are then pro­cessed fur­ther into end products. Many steel plants these days run at full steam. Pro­duc­tion down­times and busi­ness in­ter­rup­tions can have cata­strophic res­ults. If a busi­ness op­er­a­tion stops, the eco­nomic dam­age quickly runs into mil­lions. Even small fires can para­lyze an en­tire steel plant. The risk of fire is high: Hot rolling mills and cold rolling mills, weld­ing ma­chines, con­trol rooms and hy­draul­ics rooms, oil cel­lars, cable ducts, coat­ing and pick­ling sys­tems – heat meets flam­mable ma­ter­i­als al­most every­where. Flam­mable li­quids such as oil, de­pos­its and hot ma­chine parts to­gether with elec­trical ig­ni­tion sources ex­pose the pro­duc­tion ma­chines to a high risk of fire. Plant-de­pend­ent fire loads such as syn­thet­ics, ducts and oil re­serves in­crease the risk. In­vest­ments in fire pro­tec­tion are cru­cial. Flames, smoke, gas emis­sions, heat – fire has many fa­cets. Minimax has the right fire de­tect­ors for the vari­ous areas within a steel plant. Their sig­nals con­verge in the fire de­tec­tion and ex­tin­guish­ing con­trol panel, which is­sues an alarm to the people at risk and the fire bri­gade. In ad­di­tion, the Minimax panel mon­it­ors the in­stalled fire pro­tec­tion sys­tem for proper func­tion­ing and elec­tric­ally trig­gers the ex­tin­guish­ing sys­tems that are not equipped with their own trig­ger­ing ele­ments, e.g. sprink­ler sys­tems. A sprink­ler sys­tem en­sures over­all build­ing pro­tec­tion. Minimax of­fers a broad range of sprink­ler types and spe­cial sprink­lers that allow for ideal ad­apt­a­tion of the sprink­ler sys­tem to the re­spect­ive in­stall­a­tion situ­ation in the in­di­vidual pro­tec­ted areas. Areas with spe­cial fire risks or de­ploy­ment con­di­tions re­quire - either in ad­di­tion to or in­stead of the sprink­ler sys­tem - a tailored volume or equip­ment pro­tec­tion sys­tem. For this reason, de­luge sys­tems, Mini­fog water mist sys­tems, Oxeo inert gas ex­tin­guish­ing sys­tems, car­bon di­ox­ide ex­tin­guish­ing sys­tems and halo­car­bon ex­tin­guish­ing sys­tems are used in steel plants. The alarm and con­di­tion re­ports is­sued by the fire pro­tec­tion sys­tems in­stalled by Minimax, as well as by other sup­pli­ers, can be visu­al­ized on screens by the In­veron haz­ard man­age­ment sys­tem. Struc­tural fire pro­tec­tion, as well as tech­nical sys­tems by Minimax Mo­bile Ser­vices, such as fire ex­tin­guish­ers, wall hy­drants and smoke and heat ex­trac­tion sys­tems, com­plete fire pro­tec­tion in steel plants.
