prosoft-technology With the success of the first wireless Ethernet installation on mobile equipment under their belt, TKA then addressed another problem: their hot metal carriers, or HMC’s. Over 950 feet of monorail loops through the facility on which the HMC travels. The HMC drivers were also using two-way radio communication to exchange information with the Metal Lab, Melt Control Room operator and each other. The amount of time between receiving the alloy, filling the ladle, delivering the treated iron to the pouring device and getting the iron poured in the sand mold is critical. Once the iron is treated in the ladle, it has to be poured into the mold within 25 minuets or the chemistry will change and the iron in unusable. It must then be removed from the pouring device. This is called “pigging”. Depending on the chemistry and the job specifications, “fresh” treated iron may have to be added to the pouring device and possibly pigged also to flush the vessel. Iron that has been pigged has to run through the whole melt process again, thus twice the cost for melting and treating the same amount of product poured. The cost of iron at the spout is about 19 cents a pound so reprocessing an 8,000 pound ladle of iron cost us an extra $1,520.00. If the chemistries weren’t within specifications there was uncertainty as to the cause. 當(dāng)位于威斯康星州Marionette市的ThyssenKrupp Waupaca鑄造廠決定轉(zhuǎn)向無(wú)線時(shí)，他們已經(jīng)得到了六十萬(wàn)美元的投資回報(bào)率(ROI)。高架起重機(jī)小心地將8500磅重的原料放下240英尺。原料被放入十個(gè)單通道感應(yīng)電爐中的其中一個(gè)，并在2750華氏溫度下熔成鐵水。然后，熱金屬運(yùn)載器將鐵水傳送到自動(dòng)澆鑄裝置。傳送過(guò)程中，增加了合金將原料生鐵轉(zhuǎn)化成延性鐵以制成成型鑄件。 在威斯康星州Marionette市的4號(hào)工廠，每天都會(huì)熔煉出1500噸的延性鐵以制成鑄件用于汽車業(yè)、農(nóng)業(yè)、水力、重型卡車、物料輸送、電力傳輸和工程車輛。4號(hào)工廠是ThyssenKrupp Waupaca鑄造廠位于威斯康星州、印第安納州和田納西州的六個(gè)工廠中的其中一個(gè)。這六個(gè)工廠擁有3600多個(gè)雇員，每天可以熔煉出9500噸的灰鑄鐵和球墨鑄鐵。 Waupaca鑄造廠以其在產(chǎn)品加工過(guò)程中使用藝術(shù)級(jí)的技術(shù)而倍感自豪。“當(dāng)我們開(kāi)始在4號(hào)工廠尋求改善熔煉車間的效率和能力的方法時(shí)，我們發(fā)現(xiàn)，決定要如何加工事實(shí)上需要考慮三個(gè)主要的因素?！?TKA Waupaca無(wú)線自動(dòng)化項(xiàng)目的項(xiàng)目經(jīng)理Gene Johnson說(shuō)。 1. 保持記錄：為達(dá)到ISO和客戶的需求，使用的原材料和鐵的化學(xué)成分在整個(gè)產(chǎn)品加工過(guò)程中必須有跡可尋。對(duì)于熔煉車間來(lái)說(shuō)，這意味著要對(duì)從供應(yīng)商那引進(jìn)的原料、加工過(guò)程中使用的合金以及爐料中的每份原料的數(shù)量進(jìn)行記錄。當(dāng)爐料熔化時(shí)，將其從熔爐中移開(kāi)并傳送到自動(dòng)澆鑄裝置中。TKA可以找到傳送的原料與消耗的原料很少匹配的詳細(xì)記錄。 2. 精確性:TKA制造的許多零件是關(guān)鍵的安全部件。其化學(xué)性質(zhì)和尺寸大小必須準(zhǔn)確。根據(jù)他們的質(zhì)量管理系統(tǒng)的目的“為建立、證明和維持質(zhì)量系統(tǒng)與當(dāng)前ANSI/ASQC QS9002 和ISO/TS 16949版本相一致”，此問(wèn)題必須得提出來(lái)。即使這些量度是足夠完美的，記錄的信息也只能夠達(dá)到與操作員的記錄一樣良好。TKA需要盡可能減少文書(shū)工作、電話呼叫和雙向的無(wú)線電通信。 3. 降低成本：Waupaca鑄造廠以生產(chǎn)每噸鐵的工時(shí)來(lái)評(píng)估產(chǎn)品成本。當(dāng)熔煉車間開(kāi)始考
