Otomobil laCho plonje Galvalume Steel bobin inite konsantre sou pwodiksyon an nan plak ekstèn. Epesè nan espesifikasyon pwodwi yo se sitou ant 0.6 ak 1.2mm, lajè a nan plak la se sitou 800 a 1850mm, ak pi laj la ka rive nan 2000mm. Nivo pwodwi a se byen konplèks, soti nan CQ, DQ, DDQ, EDDQ (IF) rive nan BH, DP, TRIP, ak lòt plak otomobil ki gen gwo fòs -. Sèvi ak yon varyete teknoloji avanse, mòfoloji a kouch ak presizyon epesè ka kontwole avèk presizyon, tankou erè a epesè kouch se mwens pase 23g / m2. Anplis de sa, yo ka pwodwi plak asye zenk-gratis nan itilize galvanisasyon plon-gratis. Sa a kalite kouch se pa fasil yo pwodwi korozyon intergranular e li gen yon lavi sèvis long. Se poutèt sa, li apwopriye pou endistri otomobil ak aparèy elektrik. Prèske chak inite galvanize cho -dip nan Japon ekipe ak yon founo alyaj zenk-fè. Epesè estanda kouch galvanize plak alyaj zenk -fè (Galavneal) la se 160180g/m2 sou tou de bò, ak kouch alyaj la gen Fe8 pousan 12 pousan 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 .
