AutoKuum sukeldatud galvalume teraspool üksus keskendub välisplaatide tootmisele. Toote spetsifikatsioonide paksus jääb enamasti vahemikku 0,6–1,2 mm, plaadi laius on enamasti 800–1850 mm ja kõige laiem võib ulatuda 2000 mm-ni. Tootetase on üsna keerukas, alates CQ-st, DQ-st, DDQ-st, EDDQ-st (IF) kuni BH-, DP-, TRIP- ja muude autotööstuses kasutatavate ülitugevate{7}terasplaatideni. Erinevate arenenud tehnoloogiate abil saab katte morfoloogiat ja paksuse täpsust täpselt kontrollida, näiteks katte paksuse viga on alla 23 g/m2. Lisaks saab tsingi{10}vaba terasplaati toota plii{11}vaba galvaniseerimisega. Sellist kattekihti ei ole kerge tekitada teradevahelist korrosiooni ja sellel on pikk kasutusiga. Seetõttu sobib see auto- ja elektriseadmete tööstusele. Peaaegu kõik Jaapani kuum{12}}kuumtsinkimisseadmed on varustatud tsingi-raudsulami ahjuga. Tsingiga{14}}leegitud plaadi (Galavneal) tsingitud kihi standardpaksus on mõlemal küljel 160 180 g/m2 ja sulami kate sisaldab Fe8 protsenti 12 protsenti 2.
Foreign countries developed micro-alloy steel and phosphorous alloy steel in the 1970s, bidirectional DP steel and bake hardening steel in the mid-1980s, and phase transformation and induced plasticity TRIP steel in the 1990s 3. At present, the international cooperation project "Ultra-Lightweight Steel Carbody (ULSAB) Development" is proceeding smoothly. Its goal is to achieve a driving fuel consumption of 34KM/3L (US) and a car bodyweight reduction of 25 percent . The primary starting point is to adopt many high-strength and ultra-high-strength steel plates in the car body structure. The most prominent feature of the ultra-light steel car body through the large ULSAB is that it does not sacrifice performance to reduce the car's weight 4. The design basis of ultra-light steel vehicles is that the proportion of high-strength steel used in the body structure exceeds 90 percent . During the ten years from 1985 to 1995, high-strength steel in the body increased from 10 percent to 30 percent . With the surface treatment performance, The improvement of automobile life span extends from 6.7 years to 9.3 years. After deducting the energy increase in the manufacture of high-performance steel plates, 357104L of heavy oil can save a year, which is almost equivalent to saving a percentage of the energy consumption of the domestic steel industry. A few. In 2000, the use of high-strength steel plates in Japanese automobile manufacturing reached 36.3 percent .
